Why don't my comments show the correct time? How do I set my time zone?

By default, LiveJournal comment times use UTC (Coordinated Universal Time), also known as GMT (Greenwich Mean Time). If you choose to set your local time zone, comment times will display in your local time zone on pages that support comment time zones. All site scheme and system style comment pages support comment time zones, but customized comment pages with custom S2 layouts will display comment times in the default comment time zone (UTC/GMT) until the style owner adds support.

LiveJournal comment times are automatically assigned when they are posted, and cannot be set or edited to a specific time. Comment times may have additional text, such as "(local)", "UTC", or "GMT", and will appear to vary if users set different time zones.
